I had to look 'cleistogamous' up on-line. Very interesting:

"Of or relating to a flower that does not open and is self-pollinated in the bud. The fertile flowers of the violet are inconspicuous and cleistogamous, while the plant's more familiar showy flowers are usually infertile."

Is this why violets are referred to as "shy"?

I didn't know flowers did that. I'm not sure if the little red sage I have is Cedar sage, I thought it was, but it's blooms are still showing and out there.

Anyway, thanks for introducing me to a new word :-)
